As a result he is known as the "Godfather of Heavy Metal", and, because of some of his material, the "Prince of Darkness", and eventually achieved a multi-platinum solo career which revolutionized the heavy metal genre. In the early 2000s, his career as a celebrity hit a new zenith when he became a star in his own reality show, The Osbournes alongside wife/manager Sharon and two of their three children, Kelly and Jack. In August 2008, Osbourne stated in USA Today that he intends to retire from his music career after two more albums.

Osbourne was born in Aston, Birmingham, England.

Osbourne is also known for biting the head off of a bat a fan threw on stage during a concert. He was sent to the hospital for a rabies shot and claimed he thought the bat was fake.

In 1980, Osbourne debuted as a solo artist to widespread popular acclaim. Over the next two decades, his career continued to gain momentum with a continuous string of multi-platinum albums, and he has brought his notorious live show to sold-out arenas in virtually every corner of the world. As a solo artist, Osbourne has sold more than 50 million records worldwide, bringing his cumulative sales to more than 90 million albums. Blockbusters such as Black Sabbath's seminal Paranoid and Ozzy's solo albums Blizzard of Ozz and No More Tears are 4x platinum and still sell thousands of copies each week.

As the founder and star attraction of his annual Ozzfest festival tour, now in its 10th year, Ozzy continues to win over legions of new fans while at the same time building the hard rock audience by introducing standing-room-only crowds to emerging artists in the genre. The number of multi-platinum bands (which include Incubus, System of a Down, Limp Bizkit, Godsmack, Slipknot and Disturbed) that got their start or broke through due to their visibility on Ozzfest is staggering. Ozzfest, which was launched in 1996, is the longest running and most successful music festival of its kind and since its inception has sold over five million tickets for a total of more than $100 million dollars in revenue. The tour spawned the successful "Battle For Ozzfest," Ozzy and Sharon's weekly MTV series, which pits hungry young bands against one another for a shot at performing on OZZfest's worldwide tour.

Ozzy Osbourne could be seen weekly on the Emmy Award-winning series "The Osbournes" (now complete). The show is so popular in part because wife Sharon and children Kelly and Jack provide Ozzy with a nuclear family life that one would not normally associate with a star who is sometimes referred to as the "The Prince Of Darkness". On November 17 2000 Ozzy also had an appearance in a dark comedy movie "Little Nicky". Little Nicky (Adam Sandler) is the good son of the Devil and lives in Hell. Ozzy is cast as a powerful angel of God that saves the earth from evil.

The influence of Ozzy Osbourne could be felt just as strongly, if not more so, in 2005 than it was in the Seventies, Eighties and Nineties. In thirty-five years in the music business Ozzy's popularity with die-hard music lovers has never waned. In fact, it only seems to have become greater. From his days as a member of the legendary rock band Black Sabbath and throughout his tremendously successful solo career (and now, television popularity), Ozzy has transcended all boundaries and categories and is truly among the elite few who can lay claim to being called a true rock icon.

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English singer-songwriter whose career has spanned over 40 years.

Osbourne initially rose to prominence as lead vocalist of the pioneering English heavy metal band Black Sabbath, a band whose radically different, intentionally dark, doom sound spearheaded the heavy metal genre. In his subsequent solo career Osbourne achieved a multi-platinum status in addition to the one he had earned with Black Sabbath. These things are what led Osbourne to become known as the "Godfather of Heavy Metal". It was during his Sabbath days (because of their dark style of music, not because he was a satanist) that Osbourne became known as the "Prince of Darkness." Osbourne has over 15 tattoos, the most famous of which are the letters O-Z-Z-Y across the knuckles of his left hand. This was his first tattoo, created by himself with a sewing needle and pencil lead.

In the early 2000s, Osbourne's career expanded to a new medium when he became a star in his own reality show, The Osbournes, alongside wife/manager Sharon and two of their three children, Kelly and Jack.

Osbourne is currently on a worldwide tour to promote his new album Scream, released on 22 June 2010.
